Minimally Invasive Intervention for Spine Pain
The most frequently utilized approach is a medial branch block, which is felt by some to be more accurate than direct joint (facet) injections. The use of a medial branch block helps to avoid trauma to the joint complex. To perform the procedure the patient will be placed in the position that allows efficient access to the targeted joints. Once the joint level has been identified a local anesthesia is administered. Under image guidance a needle is incrementally placed to the appropriate level. After the procedure patients are usually monitored for 20-60 minutes and subsequently discharged home.
Prior to leaving, patients are questioned about their symptoms to evaluate the therapeutic response. Individuals who respond favorably to an initial injection with re-occurring pain may benefit from another set of injections or from a more aggressive approach referred to as radiofrequency rhizotomy.
Goals of the Procedure: The primary goals of the procedure are to reduce pain and improve physical capacity. Imaging studies are frequently inconclusive in the evaluation of the role of the facet joint in back pain and therefore the diagnostic facet block sometimes has to be considered.
Autonomic Nerve Blockade
Background: There are numerous autonomic sympathetic nerves around the spine. Successful blocking of sympathetic nerves at key points can help reduce deep pain patterns. Excessive sympathetic activity can perpetuate and/or accentuate back pain. Selective blocking of autonomic relay centers along the sympathetic nervous system can help break the pain cycle.
